This invention relates to that class of signaling devices used inconnection with what is known as the block signal system for governingthe movement of trains, the road being divided into sections and thesignal apparatus being so placed as to control each section in regular`order.

Figure 1 is a perspective; Fig. 2'a vertical longitudinal section brokenaway, the cap being removed; Fig. 3, a view ofthe signal slides andcages; Fig. 4, a horizontal transverse section in the plane a: w,Fig. 1. Fig. 5 is an elevation, with one side of the outerinclosing-case removed, showing the interior; and Fig. 6 a hori-A zontaltransverse section in the plane y y, Fig. 5.

Referring to the drawings, A represents an outer i'nclosing-case of arectangular form, having four equal sides; but may be of any otherdesired form that convenience may require, the inclosing-case servingthe purpose of supporting and protecting the signal devices l fromatmospheric changes. The lower portion of one side of the outer caseconsists of the hinged door A', which conveniently admits of access tothe interior, in order to replace or remove the signal-lamp, and forsuch other purposes as may be required to keep the apparatus in properworking order. The lower inclosed end is provided with elongatedapertures for the passa-ge of the vertically-sliding signal-boards B Bas they are adjusted to different positions. The upper end is inclosedby the metallic ventilator cap or hood A2, which is perforated for theescape of the gases from the signal-lamp, placed on the inside bottom ofthe apparatus, as indicated by the dotted lines in Fig. 5 of thedrawings. The two sides of the inclosing-case, adjacent to the hingeddoor A, are prpvided with the circular openings C2 G3, covered withglass, forming a bulls-eye, which reflects the light in both directionson the track. The smalleropening, B6, is placed in that side of theouter inclosing-case that is opposite the hinged door A',

said opening being covered withnl glass, and making proper provision forthe signal-operator to observe the condition of the lamp, and whetherthe proper signal is being displayed.

lhe outer casing, A, is ordinarily constructed of wood and painted withany color desired. On the inside of this case is placed the metallicilue C, leaving considerable space all around between the inclosed andinclosing walls for the reception and movement of the signal devices, asshown in Figs. Zand 5 of the drawings. This iiue is of a formcorresponding tothe outer case, and is provided with a rectangularopening closed by the vertical slide G. `The signal-lamp is placed onthe inside of the metallic ilue, and is thus doubly protected from theinclemency of the weather. The upper end of this flue is contracted,andprojects above the upper end of the outer inclosing-case into themetal cap A2,` which is` provided with the perforated escapetube A3, asshown in Fig. 5 of the drawings. The lower part of the metal ilue C isprovided with circular openings corresponding to similar openings in theouter inclosing-case, A. rllhe adjustable signal-boards B B are adaptedto move in a vertical plane on the inside ofthe inclosing-case A. Thelower ends of the signal-boards lare provid ed with the circularopenings B2 B3, which correspond to similar openings in thel outer case,A, andthelinner case or metallic flue, C, the different openings beingopposite Veach other when the signal-boards are vin their normalposition, as shown in Fig. l of the drawings, a white light beingdisplayed from both sides of the apparatus. The signal board or slide Bis painted red, the upper end being formed with the square opensignal-box D, as shown in Fig. 3 of the drawings. The upper endofthesignal-board Bforms one side of the square bon D, which is open atboth ends and incloses the' metallic rlue C, that forms a guide for thevertical moving signal devices. The upper end of the signalboard,forming one side of the box D, is provided with the rectangular rabbetedrecess a,

IOO

the opposite side of the box being provided with a similar recess. Theserecesses are intended to receive and retain colored signalsheets ofglass, which slide into place from the upper end. The color of thesheets of glass B4 in the box D is red, and that is the signal displayedwhen the box D is dropped down into the same horizontal plane with thesignal-lamp, and is seen from both sides, the signal-board being the daysignal. The companion signal-board B' and the signal-box D' are of thesame general construction as the box just described, the box D' beingsomewhat larger in order to slide over the box D, thus forming a boxwithin a box. The box D' is provided with the glass sheets B5, of agreen shade, the day signal-board being ofthe same color.

These signal devices are operated and controlled by, means ofthe cordsa' a'-, which pass over the sheaves c 3 ai, as shown in Fig. 2 of thedrawings. rlhe inside ends of these cords are connected to thecross-bars b b', attached to the upper ends of the signal-boxes, whilethe opposite ends pass out through perforations in the cap A2, and leadto the place where the device is to be operated from. The sheaves a3 a*are journaled in the brackets b2 b, which are inserted in the under sideof the bridge E, which is supported by the vertical ends d d', attachedto the upper end of the outer case, as shown in Fig. 2 of the drawings.By slacking on the cords the signals will drop by force of gravity, andare easily and conveniently returned to their normal position by meansof the controlling cords. The signallamp always remains stationary, andany number of different-colored signals can be displayed from the sameapparatus by simply increasing the dimensions of the outerinclosing-case and multiplying to any extent the number of signalboxeson the inside, thus forming a double track block and train-order signal,whereby one track can be blocked and the other clear, or theblock-signal can be displayed for one track and train-orders for theother, or both trains blocked, or train-orders for both tracks, ortrain-orders for one track and the other clear, as may be required atthe particular time.

The apparatus is easily and cheaply constructed, the colored glasseasily replaced if broken, no parts of the device are liable to get outof order, and the different signalglasses are protected from smoke anddust.

If desirable, the apparatus may be so constructed as to display theday-signal boards in a horizontal plane.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isa 1. In a railway signal apparatus, thecombination, with an outer inclosing rectangular case provided withtransparent .openings at the lower end and a cap and escape-tube at theupper end, of a rectangular metallic flue arranged centrally on theinside of said case, said flue being provided with correspondingopenings and forming a receptacle for a stationary lamp, and the squaresignal-boxes D D', arranged one 'within the other and inclosing saidflue, and adapted to have a vertical movement on the interior of saidcase, substantially as set forth.

The combination, with the inclosing-case A, of the day-signal boards BB', adapted to have a vertical movement on the interior of said case,and provided on the upper inner ends with the signal boxes or cages DD', substantially as d escribcd.

3. The combination, with the case A, of the signal-boards B B', adaptedto project from the lower end of said casein a vertical plane, and thesquaresignal-boxes D D', secured to the interior upper ends of saidboards and adapted to move simultaneously therewith, said boxes beingopen at the top and bottom and. arranged to have an independentadjustment relative to cach other for the purpose of displayingldifferent signals, substantially as set forth.
